Cisco's New Innovations for Cisco Campus Communications Fabric

To meet business demands and simplify operational management, Cisco® has just introduced new modular Catalyst® switch improvements to help companies take full advantage of real-time communication.

• "Cisco Catalyst 6500 Series Virtual Switching System (VSS)1440 enabled by the Virtual Switching Supervisor Engine 720 with 10 Gigabit Ethernet: Effectively combining multiple Catalyst 6500 switches into one, the VSS 1440 scales system bandwidth capacity to as much as 1.44 terabits per second (Tbps). It also simplifies operational management by enabling multiple Cisco Catalyst 6500 Series Switches to share a single-point of management, single routing instance and single IP address, as well as eliminating the dependence on spanning-tree and first-hop redundancy protocols like the Virtual Router Redundancy Protocol (VRRP). In addition, it provides investment enhancement through offering two times the previous scalability plus higher availability.

   

   

• Cisco Catalyst 4500 E-Series with CenterFlex technology: Delivering 320 gigabits per second (Gps) and a fourfold increase in per-slot bandwidth using its unique centralized and flexible architecture, the Catalyst 4500 E-Series provides expanded service capacity, flexibility and performance to help enable companies to optimize their unified networks for rich applications, while offering exceptional investment enhancement and protection with a design that maximizes forward and backward compatibility.

   

Simplifying Operational Management:
Cisco 6500 Virtual Switching System 1440

Cisco raises the flagship Catalyst 6500 Series platform to the next level with the Cisco Catalyst 6500 VSS 1440 innovation based on 11 new patented concepts that span software and hardware technologies. Upgrading to the Cisco Catalyst 6500 Series Virtual Switching Supervisor Engine 720 with integrated 10 Gigabit Ethernet uplinks helps enable existing Cisco Catalyst 6500 Series switching investments and multilayer switching architectures to be enhanced with VSS capabilities that doubles system bandwidth capacity.

The Cisco 6500 VSS 1440 innovation allows two Cisco Catalyst 6500 Series Switches to look and act like a single virtual switch, and it scales overall system bandwidth capacity to 1.44 Tbps by activating all available bandwidth across the two Catalyst 6500 switches. It helps increase operational efficiency and simplifies network management by facilitating a single point of configuration and management of the VSS domain. Cisco VSS 1440 also boosts nonstop communications by delivering deterministic, subsecond Layer 2 link recovery through interchassis stateful failovers and the predictable resilience of multichassis Etherchannel technology.

Increasing Performance with Investment Enhancement: Cisco Catalyst 4500-E Series

The Cisco Catalyst 4500 E-Series with CenterFlex technology is a next-generation extension to the Cisco Catalyst 4500 Series delivering nonstopcommunications with four times the bandwidth per slot improvements, operational control and exceptional investment enhancement.

The Catalyst 4500 E-Series includes the Supervisor6-E, three new E-Series 10 Gigabit Ethernet and 10/100/1000 PoE line cards that quadruple bandwidth per slot, and four new E-Series chassis.

Extensive forward and backward compatibility between Cisco Catalyst 4500 generations allows customers to mix and match existing and E-Series line cards without performance degradation. Upgrading to the new Supervisor 6-E adds CenterFlex features to previously deployed line-card ports. These new CenterFlex features, including IPv6 in hardware, allow customers to meet changing business needs with minimum investment and business disruption"
